Temperature Factors in Antigua and Barbuda

Average Temperature: Consistently between 26°C to 30°C (79°F to 86°F)
Thermal Impact: Though higher temperatures may cause a minor reduction in panel efficiency, the high solar radiation offsets this performance loss

Recommendation: Use temperature-tolerant solar panels, with installation practices that ensure good airflow beneath modules to reduce heat buildup.

Energy Demand and Grid Situation in Antigua and Barbuda

National Energy Demand: Dominated by residential cooling, hospitality sector, and public infrastructure
Electricity Provider: Antigua Public Utilities Authority (APUA) supplies grid power, primarily through diesel generators
Energy Cost: Electricity prices remain high compared to global averages, prompting increased interest in solar energy adoption

Antigua and Barbuda has also experienced grid outages during storm seasons, reinforcing the need for resilient solar + storage systems.

Preferred System Type in Antigua and Barbuda

Hybrid Solar Systems: Combining grid-tied PV with battery backup is ideal for homes, resorts, and government facilities
Off-Grid Systems: Suitable for remote properties, farms, and island areas where grid connection is expensive or unavailable
Microgrid Development: Some initiatives have explored solar-based community microgrids to improve energy access and resilience

Dust and Sand Factor in Antigua and Barbuda

Dust Level: Generally low, with occasional Saharan dust events affecting the eastern Caribbean
Performance Impact: Minimal impact overall, though cleaning panels periodically during the dusty season helps optimize output

Humidity and Rainfall (Humidity Factor) in Antigua and Barbuda

Humidity: Average relative humidity ranges from 75% to 85%
Rainfall Pattern: Heaviest between August and November, during the Atlantic hurricane season
Moisture Risk: Persistent moisture can affect connectors, mounts, and battery enclosures

Recommendation: Use marine-grade materials and IP-rated waterproof components to withstand humid and wet conditions.

Ocean (Salt Corrosion Factor) in Antigua and Barbuda

Salt Exposure: High, especially in coastal areas where sea spray and salt-laden wind are frequent
Corrosion Concern: Salt can cause premature degradation of system components if not properly protected

Recommendation: Choose corrosion-resistant materials, such as anodized aluminum, stainless steel hardware, and sealed electronics designed for coastal installations.

Government Policies and Solar Incentives in Antigua and Barbuda

National Renewable Energy Target: Antigua and Barbuda has pledged to reach 50% renewable energy penetration in electricity generation
Supportive Policy Framework: Includes net metering programs, tax exemptions, and renewable energy development plans
International Collaboration: The country has partnered with organizations like IRENA and CARICOM to support clean energy adoption

The government actively promotes solar as a tool for economic resilience and climate adaptation, especially following recent hurricane impacts.

ROI on Solar Systems in Antigua and Barbuda

ROI Period: Generally 4 to 6 years, depending on system size and local fuel prices
Cost Reduction: Users can see electricity cost savings of 60–80%, particularly when combining solar PV with battery storage
Sustainability Bonus: Solar systems also support disaster recovery and energy independence
